Abstract (en)
A polymeric composition includes a silane functionalized polyolefin, a brominated flame retardant having a Temperature of 5% Mass Loss from 300°C to 700°C as measured according to Thermogravimetric Analysis, wherein the brominated flame retardant is polymeric and has a weight average molecular weight of from 1,000 g/mol to 30,000 g/mol as measured using Gel Permeation Chromatography, and antimony trioxide. The polymeric composition has an antimony (Sb) to bromine (Br) molar ratio (Sb:Br molar ratio) of 0.35 to 0.98.
